Weather experts on the Leeward Islands, including Puerto Rico, are keeping close watch as Erin lurches toward the Caribbean and is on track to become a major hurricane.

Tropical Storm Erin is still moving quickly westward and is forecast to become a hurricane in a few days over the central tropical Atlantic, the NHC said.

The NHC forecast advisory predicts Erin will continue westward today before bending west‑northwest tonight and through the weekend as a weakness develops in the subtropical ridge. Forecast positions show the storm moving from 16.
